VTrak M310p, M210p Product Manual

To make use of logical drives greater than 2TB in size, a larger sector size is required. The table below correlates sector size with logical drive capacity.

Logical Drive Size

Sector Size

 

 

8 to 16 TB

4096 bytes (4 KB)

 

 

4 to 8 TB

2048 bytes (2 KB)

 

 

2 to 4 TB

1024 bytes (1 KB)

 

 

0 to 2 TB

512 bytes (512 B)

 

 

When you create a Disk Array using the Express or Advanced methods, and when you create a Logical Drive, you can specify sector size of 512 B; 1, 2, or 4 KB. 512 B is the default.

In most cases, you should select the smallest sector size that will allow full use of the physical disk drives in your disk array.

Because logical drives can be expanded, you may encounter a situation where the usable capacity of your expanded logical drive is reduced by the addressing issue described above. There are two alternatives:

Limit your logical drive expansion to within the limits described in the chart.

Back up your data, then delete your existing logical drive and create a new one with a larger sector size.

Cache Policy

As it is used with VTrak, the term cache refers to any of several kinds of high- speed, volatile memory that hold data moving from your computer to the physical drives or vice-versa. Cache is important because it can read and write data much faster than a physical drive. There are read caches, which hold data as it is read from a physical drive; and write caches, which hold data as it is written to a physical drive.

In order to tune the cache for best performance in different applications, user- adjustable settings are provided. Cache settings are made in conjunction with logical drives:

When you create a logical drive. See “Create a Logical Drive” on page 98

On an existing logical drive. See “Logical Drive Settings” on page 107

Read Cache Policy

Read Cache – The read cache is enabled.

Promise Technology has established itself as a strong player in the storage solutions market, particularly with its VTrak series of storage systems. Among the notable products in this lineup are the VTrak M310P and M210P models, designed to deliver efficiency, scalability, and high performance for businesses of all sizes.

The Promise VTrak M310P is a high-performance storage solution that emphasizes speed and versatility. This model supports both SAS and SATA drives, enabling enterprises to tailor their storage needs based on workload requirements. It is built with an advanced RAID engine that provides multiple RAID levels, including RAID 0, 1, 5, 6, 10, 50, and 60, ensuring data redundancy and protection against drive failures. The M310P can accommodate up to 96TB of raw storage when fully populated, catering to environments that require large amounts of data retention and quick access times.

Key features of the VTrak M310P include the intuitive management interface, which simplifies storage provisioning and monitoring. This model also incorporates Promise's innovative "HyperRAID" technology, which enhances performance by optimizing I/O operations and providing real-time analytics and reporting. Additionally, the M310P supports a variety of host connection interfaces, including iSCSI, Fibre Channel, and InfiniBand, allowing seamless integration into existing infrastructure.

On the other hand, the VTrak M210P is tailored for a slightly different audience, focusing on small to medium-sized businesses that require reliable and cost-effective storage solutions. The M210P retains several high-end features found in its bigger counterpart while offering a more budget-friendly option. This model also supports a mix of SAS and SATA drives and includes RAID capabilities similar to the M310P for data protection.

The M210P provides a robust set of management tools designed for ease of use, including automated alerts and comprehensive reporting capabilities. Its compact design and reliable performance make it ideal for remote office locations or data centers where space is a premium. Furthermore, the model incorporates advanced power management features to reduce energy consumption without compromising performance.

Both the M310P and M210P are built with scalability in mind, allowing businesses to easily expand their storage capacity as data needs grow. With a focus on durability, performance, and advanced technology, Promise Technology’s VTrak systems are well-positioned to meet the evolving demands of modern data storage. Whether for large enterprises or smaller organizations, these products offer solutions that enhance productivity and ensure data integrity.
